Your plan will work, but a couple of things I'd like to mention. The BIOS flash of the mobo probably isn't necessary, and could be left until after Windows install. Also, OCZ's firmware updates come on their own .iso which can be burned to a CD/DVD, so no recovery disc should be needed. Make sure your SSD is the only drive connected while installing Windows. And don't forget to move your page file to a HDD.

I am plugging the OCZ SSD in to the board on SATA_0 and the HDD's on SATA_1 and SATA_2 sockets. These will use the Intel ICH10R chip.
I'm not sure where the Optical drive should plug in. I am thinking it should be on the SATA2 3Gb/s sockets....SATA_8. This will also use the Intel chip.
